Finland-based photographer Janne Parviainen had this mad idea of tracing entire rooms with one LED and now he has finally gotten started. He calls his new series “Light Topography” and believe it or not, all of his shots are straight from the camera. It takes as long as half an hour to create such long exposure photograph and he likes to joke that one must be totally mad to be doing that.
“You know you are totally and utterly mad when you are tracing a whole room with one LED alone in the middle of the night,” says Janne.
